Abstract

Commercial dishwashers are among the most important products for commercial kitchen personnel as they clean dirty products (plates, glasses, cutlery, etc.) in a short time (between 1 and 4 minutes according to the program). In recent years, customers’ demands for energy-saving products have been increasing. Therefore, instead of using the electrical energy to be obtained after the combustion of natural gas in power plants, the use of direct natural gas in a commercial dishwasher contributes to reducing the carbon footprint. In this study, the original design studies of the combustion system of the innovative commercial dishwasher prototype using water heated with gas were carried out. For the first time in our country, the system that enables the heating of water with gas was designed as a module other than the existing commercial dishwasher. An independent combustion system has been developed to provide easy use to other commercial dishwashers on the market. Simulation studies have been used effectively in the design verification phase in order to provide the most efficient combustion conditions for different gases (natural gas and LPG) in the original designed combustion system. Combustion analyses were carried out by parametric study for different operating conditions. In the innovative commercial dishwasher prototype that uses water heated with gas, optimum temperature values have been obtained for effective washing at the water inlet and water outlet points of the uniquely designed combustion system. As a result of the tests and evaluations, the most effective working range of the innovative prototype was determined.
